Document Type and Number:
WIPO Patent Application WO/2020/218505
Kind Code:
A1
Abstract:
The present invention provides a simplified structure for fixing a bearing for supporting an output shaft to a housing. A speed reducer (2) includes a housing (10), an output shaft (20), a bearing (30) supporting the output shaft (20) in the housing (10), and an outer fixing part (40) fixing the bearing (30) in the housing (10). The outer fixing part (40) has a ring-shaped outer engaged part (41) formed on an inner peripheral surface (12a) of an opening (12), a ring-shaped receiving part (42) formed in the housing (10) and projecting into the inner peripheral side, and an outer fixing body (43) that is a ring-shaped member having a ring-shaped outer engaging part 44 formed to be engageable with the outer engaged part 41. The outer receiving part (42) is formed on the inner side of the outer engaged part (41) in the housing (10), and is formed so as to be capable of contacting an outer ring (32) of the bearing (30). The outer fixing body 43 is formed so as to be capable of contacting the outer ring (32) of the bearing (30) when the outer engaging part (44) is engaged with the outer engaged part (41).
